' In Germany November 8, 1937 This invention relates to cylinder printing machines, and more particularly to certain improvements in the mechanism for rotating the rotary elements of the inking apparatus in such machines.

As a rule, the inking apparatus of cylinder printing machines is operated irom' the reciproeating type carriage of the machine. However, it has already been proposed in single-revolution and double-revolution cylinder printing machines to operate the inking apparatus from the impression cylinder. In this case, the inking apparatus is operated. so that its elements rotate at uniform velocity and permanently in a. given direction, and the inkersof the apparatus are. placed in active position with respect to the .form only when the carriage moves in a given direction.

It is an object of the invention to provide an improved mechanism for rotating the rotary elements of the inking apparatus of cylinder printing machines of all kinds, including, for instance, stop cylindermachines in which the type carriage moves at variable velocity throughout its stroke.

. To this end, in a machine of the kind described, mechanism is provided and operatively connected to the drive of the machine, for rotating the elements of the inking apparatus permanently in the same direction of rotation independently of the motion of the carriage, and in combination with this mechanism means operatively connected to-the drive of the machine is arranged for regulating the rotation of the elements in conformity with the variable motion of the carriage.

By these means, the normally uniform rotation of the elements in the inking apparatus is regulated and adapted to the varying motion of the carriage.

It is another object of the invention to provide for an exclusively continuous, i. e., non-regu lated,, rotation of the ele'mentswhen the carriage has been arrested.

- operated when the carriage is arrested.

To this 'end,',manual means is provided for making and breaking the connection of the regulating means and the drive, and such means is It is another object of the invention to provide improved inkers in the hiking apparatus.

To this eridpthe diameter of the inkers is so deternfined that their perimeter: substantially. corresponds to the maximum printing length of themachine.

It is' another object-of the invention to so mange the inke s t t e sa p nt: on the for instance, 5% revolutions, from the moment 'inkers, that is, whether I 'Fig. 1 is a side elevation showing a portion of the regulating means areactive.

perimeter of the inkers co-incide with the same points of the form not at all, or only rarely. This effects a good inking of the form and is an important improvement as compared with the known inking apparatus in which the same points of the inkers invariably coincide with the same points of the form.

To achieve this object, the inkers are arranged v to perform an incomplete number of-revolutions,

they are met by the form during the forward motion of the carriage, to the moment such meeting occurs again.

It is another object of the invention to provide improved means for moving the inkers out 15 of their inking position, i. e., away from the form, when the carriage is arrested, irrespective of the position of the form with respect to the the form is below the inkers, or not. 20

To this end, automatic means operatively connected to the manual means for making and breaking the connection of the regulating means and the drive, is provided for moving the inkers out of their inking position when the manual means is operated for breaking the connection.

.By providing for the permanent rotation of the rotary elements in the inking apparatus after the carriage has been arrested, it is possible to ink and to adjust the parts of the inking appa- 30 ratus while the carriage is stationary. Another advantage of the invention resides in that the carriage with the form can be reversed immediately after leaving the inkers, since in an inking apparatus according to the invention the .last inker is provided with fresh ink all over its perimeter and there is ample time to supply with fresh ink the entire perimeter of the inkerfor inkers. 4 I

Fig. 9 is a velocity diagram for the carriage of a single and double-revolution cylinder machine.

Referring now to the drawings, and first to Fig. 1, I8 is the frame of the stop cylinder machine,

of usual construction, and is its type carriage.v

The means for reciprocating the carriage 4 comprises, as usually, a connecting rod 6, Fig. 2, on the crank pin of a driving spur gear 2. The shaft 5 of the driving spur gear is mountedto rotate in a bearing bracket 38. Rotation is imparted to the driving spur gear 2 by a pinion 4 on the main driving shaft 3 which is mounted to rotate in the frame H3. The drivingspur gear 2 is secured on its subsidiary driving shaft 5. A combined fly wheel and pulley is free to rotate about the main driving shaft 3 and is connected to the shaft by a coupling C, of known construction and therefore not shown in detail. When the coupling C is thrown in, as shown in Fig. 2, the pulley is connected to the main driving shaft 3 and the carriage is reciprocated by its reciprocating means 2 and 6. When the coupling is thrown out, as shown in Fig. 3, the car-- riage I is stationary. The pulley 7 is hollow and a clutch member ID, with clutching parts, for instance claws, is secured to the inner side of its web. The clutch member In may be integral with the web, if desired. A clutch sleeve I2 is splined on the shaft 3. At its outer end which is of larger diameter, it supports a clutch plate I I, with clutching parts projecting from both its sides, and at its inner end it is made with a pinion l3. A clutch disk I4 is placed on the shaft 3 within the larger end of the sleeve l2, and adapted to cooperate with'the clutching parts on the inner side of the clutch plate I I. The larger end of the sleeve I2 is grooved on its outer perimeter, and a pin l5 at the free end of an arm |6 engages in the groove. The arm I6 is fulcrumed on a stud l9 which is supported by a bracket IT on the frame I8 of the machine. A manual member, or handle, 20 is seated on the stud l5 and equipped with an annular member 2| which is recessed for the reception of a sector 22 on the arm' Hi. The recess is somewhat wider than the sector and when the handle 20 is swung about the stud IS in the direction of the arrow 23, there is an idle movement between the handle 20 and the arm l6, and then the arm I6 is swung in the direction of the arrow 24. A dog 25 is rigidly connected to the handle 20 at its lower side for cooperation with a pin or roller 26 on 2. lug 21. The lug 21 is supported by a coupling rod 28 which is arranged to be shifted longitudinally on the frame |8, Figs. 3 and 4. The dog 25 and the rod 28 form part of the automatic means which is operatively connected to the manual means, or handle, 20, for moving the inkers out of their inking position, as mentioned in the introduction.

The pinion I3 on the clutch sleeve |2 meshes with a larger spur gear 29 which is free to turn on a stud shaft 30 secured in the frame I 8, and the teeth of the pinion are so long that it does not move out of mesh with the spur gear- 29 when the sleeve. I2 is shifted by the means described. A smaller spur gear 3| is also free to turn on the stud shaft 30. Arranged to swing about the stud shaft 38 at opposite sides of the spur gear unit are the bosses of two plates 32 making up together a rocking frame. A pinion 33, with a double row of teetn, turns freely on a transverse stay in the frame 32. One of its rows of teeth meshes with the larger spur gear 29 and the other row meshes with a pinion 34 which rotates about a'stud in the frame 32 and, in turn, meshes with the smaller spur gear 3|. Pivoted on the outer end of the stud the pinion 34 rotates about, is one end of a coupling rod 35 whose other end is pivotally connected to a rocking arm 36. This arm is secured on a shaft 31 which is mounted to turn in the bearing bracket 38.

As described, the pinion 33 is in permanent mesh with the larger spur gear 29, and the pinion 34 is in permanent mesh with the smaller spur gear 3|. A pinion 42, Fig. 6, is rotated from the smaller pinion 3| through a train of gears 39, 40, Ml, 4|, of usual construction. The pinion 42 is free to turn on the boss of a spur gear 43, and this boss is free to turn on the fixed shaft 44 of an inking cylinder 45in the inking apparatus A. The spur gear 43 is rotated by a spur gear 46 secured on the shaft I42 of the two spur gears i4] and 4|. The pinion 42 drives the inking cylinder 45 by a pin 41 making a sliding fit in a hole in the end wall of the inking cylinder. Through a train of gears which will not be described in detail, as it is of usual construction, the rotation of the spur gear 43 is transmitted to a spur gear 48 which is free to rotate on the shaft 49 of a ductor cylinder 50, Figs. 1, 4, and 5. The ductor cylinder is secured on its shaft 43. A ratchet wheel 5| is keyed on the shaft 49, and a pawl 52 pivoted on the spur gear 48 engages in the ratchet wheel under the action of a spring, not shown.

Through the said train of gears, the ductor cylinder 50 is permanently rotated in the direction of the arrow 53, Fig. 4. A vibrator 54 is arranged to cooperate with the ductor cylinder 50, and supported at the upper end of a bellcrank 88 fulcrumed on the frame at 55. A spring 56 tends to hold the vibrator 54 against the ductor cylinder 50.

Forming part of the inking apparatus are distributing rollers 51. Two pairs of such rollers have been shown but it is understood that any number may be provided, for transferring ink to the inking cylinder 45. Two inker rollers 58 are in contact with the inking cylinder 45. The diameter of the inkers 58 is so determined, that their perimeter, as mentioned, is substantially equal to the maximum printing length of the machine. More than two inkers might obviously be provided but two are normally sufficient. Each inker 58 is mounted adjustably for rotation in the free end of an arm 59. The arms are mounted to turn, scissors fashion, about the fixed shaft 44 of the inking cylinder 45, and have extensions 68 beyond the shaft. Two pins 6| are arranged for cooperation with the two extensions 6|) of the arms .59, and are supported by an arm 62. The boss 62a of the arm 62 is mounted to swing about a rivet 62b in a wall of the frame |8, and the arm 62 is swung by a linli- 63 which is pivotally connected to the shorter arm 64 of a lever which is pivoted on the frame of the machine at 66. The pins 6 I are not in direct engagement with the extensions 60 but bear against bufferplates 61 which are supported on the inking cylinder shaft 44, and can be adjusted with respect to the extensionsfll by screws '68. The buffer plates serve ing nearertoget'her to a greater or lesser extent,

coupling according to variation in thediameter of the inkers 59 due to wear. A spring 99 attachedto the arms 59 tends to'pull the inkers 58 together and into their inking position, Fig. .1, in which they ink the form .on the carriage l advancing in the direction of the arrow 19. e

The rocking arm 96 which, as will be remembered, is connected to the rocking frame 32 by the coupling rod 35, is controlled by an arm ll on the inner end of its shaft 31 with a pin 12 at its free end engaging in a cam groove 19 in the inner face of the driving spur gear 2. The groove is partly concentric to the axis'of the subsidiary shaft 5, and partly eccentric, and is of such configuration that rotation of the spur gear 2 in the direction of the arrow." causesthe arms 1 i and 96 to oscillate in the direction of the double arrow I4r Fig. 1, which, through the medium of the rod 35, causes the rocking frame 92 to perform a similar oscillation about the stud shaft 30, and the pinions 33 and. 34 in the rocking frame 92 to roll toand fro on the respective spur gears and SI, resulting in the operation which will be described below.

The rocking frame :2, with its pinions as and 34 and the parts connected thereto, as shown separately in Fig. 7, make up the regulating means referred to, by which the otherwise uniform rotation imparted to the rotary elements of the inking apparatus A by the train of gears connecte'd to the spur gears their is adapted to the varying motionof the carriage. l.

A cam plate 151s secured on that end of the subsidiary shaft 5 which is opposite the driving spur gear 2', Figs. 1, 2, and 4, and obviously the cam plate 15 rotates with the. spur gear 2 in the TI, and equipped with a the frame crthe machine.

'rocating slide 92 A plate 91 with scam groove 94 is {a lowering or raising of direct-ionpi the arrow I5. An arm 19, as best seen in Fig. 4, is fulcr'uined on the frame It at roller 119 for cooperation with the cam plate 15'. The route which supports the roller 26 i'or cooperation. with the dog 25 on thehandle 29, is connected 4 with its front end, and a spring 99 engaging the arm 19 at its upper end holds the roller 19 against the edge of thecam plate 15; I

The rearend of the rod 2 is plyotally connected to one arm of a bellcrank llfulcrumed on and a vertically recipls 'pivotally connected to the other arn'i.

secured to the'slide 92, and the longerarm 95 o the lever to whose shorter arm the link '59 is-connected, engages in the groove with a pin 85. By these means, the vertical reciprocation or the slide 92 causes horizontal reciprocationof the link 6: in its" longitudinal direction, and this. as will be explained below, has for its consequence the inkers a a will be described. I

A dog 95 is secured to theslide 9? and, in the position illustrated in Fig. 1, engages below a. pin 91 -on the bellcrank.-'89 which supports the vibrator 54. The vibrator is now removed from the ductor cylinder 59 againstthe action of the spring as and held against the first distributing roller 51. Ahandle I95 is provided on that arm'- of the bellcrank as which is equipped with the distributingrollers 51' are to the mix 19' at the some pin 91. A roller 99 on the bellcrank 99 cooperates with a sector-shaped cam 99 which is free toturn on the shaft 49 of the ductor cylinder 59 andis equipped with a spring catch 9| for holding the .cani 991 in various positions with respect to a toothed sector 92 which is integral with an arm 99 and is also free to turn on the shaft 49. The upper end of the slide 91 is connected to the free endof the arm 93.

- The connection between the ductor cylinder 59 and the spur gear 48 is broken by throwing out the pawl 52 fromdhe ratchet wheel 5| which is not end of the sleeve is tapered at 95 and this tapered end, upon the .hand wheel 94' being pushed inwardly in the direction of the arrow 95, strikes a pin 91 on the pawl 52 and disengages it from the ratchet wheel 5|.

The inking cylinder 45 is to be shifted on its shaft 44 while being rotated at uniform velocity by the pinion 42 and the pin 41. For'this purpose, the means illustrated in Fig. 6 is provided. An annular cam plate 95 is secured on the boss of the spur gear 43, and an endless groove 99 is-arranged in the perimeter of the cam plate at an angle to the axis of the shaft 44. A pin I00 in the end plate of the inking cylinder 45 engages in the groove 99. Since the velocities of thepinion 42 and the spur gear the, cam plate 98 and the inking cylinder 45, are diiferent, the inking cylinder 45 is shifted along the shaft 44 bythe groove'99 while rotating. The

cylinder in mannerper se known.

. The, operation'of the machine is as follows:- Assume that the carriage l is in the position illustrated in Fig. l in which it begins to advance on it's forward stroke in the direction of the arrow Ill for, inking the, form. The inkers 59 then assum'e the-positionii illustrated in Fig. l and rotat'e in the direction of the arrows, so that they will ink the form as itmoves pasttheni in the direction 10. In this position of the parts, the vibrator 54 is in contact with the first distributing roller 51, as also shown in Fig. l and the slide 82 has been elevated into its topmost position by clutch disk [4 which is secured on the main driving shaft 9, as shown in Fig. '2, and when'the 43, and consequently of shifted by the inki motor 8 is started to rotate the main driving shaft 3 clockwise, as indicated by the. arrow in Fig. 1, through the pulley l and the coupling 0, the carriage l issta'rted in the direction or the arrow "by the carriage reciprocating means 2, 9, and" time, through the mechanism '29, 9|, i the-inking cylinder 45 is rotated clock.- wise, assindicated by the; arrow, and the inkers 59 are rotated anti-clockwise by the cylinder.v The form. is'now inked by the inkers 59. Since in a stop cylinder printing machine, as illustrated, the

carriage I does not move uniformly but according to the sinus curve lIHdnFig; 8, a similar variable motion is imparted to the rotary'members 75 0f the inking apparatus A, in strict conformity with the motion of the carriage I. This is effected by the correspondingly shaped cam groove 13 in the driving spur gear 2 while the spur gear rotates anti-clockwise in the direction I6. The cam groove I3 oscillates the rocking arm 36 whose oscillation is transmitted to the rocking frame 32 by the coupling rod 35, so that the rocking frame 32 also oscillates aboutthe stud shaft 30.

When the rod 35 moves to the left in the direction of the arrow I02 in Fig. 1, the rocking frame 32, with the pinions 33 and 34, moves in the same direction and thereby the pinion 33 is rotated at a higher speed than that at which it is driven by the larger spur gear 29 which is rotated at constant speed by the pinion I3 on the clutch sleeve I2. This acceleration is transmitted to the smaller spur gear 3| through the pinion 34, and finally to the rotary elements of the inking apparatus A. When the rod 35 is moved against the arrow I02 by the cam'groove I3, obviously a corresponding deceleration ofthe inkingapparatus A occurs, and while the concentric semi-circular portion of the groove moves past the roller 72, the rocking arm 36 and the rocking frame 32 are not influenced, and the inking apparatus is driven uniformly. This uniform motion is imparted to the inking apparatus A from the moment the form has moved beyond the inkers 58 in the direction of the arrow I0, and throughout the return of the carriage against the arrow I0, Fig. 4, since during this period the inkers 58 are clear of the form. In this manner, the velocity curve I03 in Fig. 8 is easily produced.

The configuration of the cam plate I5 is such that in rotating in the direction of the arrow 16 from the position in Fig. 1 it shifts the rod 28 to the right in the direction of the arrow I04 in Fig. 1 against the spring 80. This causes the slide 82 to descend and its dog 86 to relase the pin 81 of the bellcrank 88. The spring 56 is now free to force the vibrator 54 against the ductor cylinder 50 and to receive fresh ink. This position of parts is illustrated in Fig. 4. This is the lowermost position of the slide 82 which ceases to de scend when the form with the carriage I has left the inking apparatus A and is in theposition according to Fig. 4. At the same time, the descending cam plate 83 swings the double-armed lever 64, 65 from the position in Fig. 1 into that in Fig. 4 in which the link 63 has moved to the right and the arm 62 assumes the inclined position in Fig. 4. Its pins 62 spread apart the inker arms 59 against their spring 69, lifting the inkers 58 beyond the upper surface of the form. In this position, the inkers 58 remain until the form has returned into its initial position, Fig. 1, and no inking occurs during the return of the carriage I.

The cam plate I5 when turning from the position in Fig. 4 in the direction 16 allows the spring to gradually elevate the slide 82 until the concentric portion of the cam plate engages the roller 18. The consequence is that before the roller I8 is engaged by the concentric portion, the sector cam has been turned in the direction of the arrow in Fig. 4 by the arm 83 of the toothed sector 92, that the cam engages the roller 89 on the bellcrank 88 and removes the vibrator 54 from. the ductor roller 50 before the ascending dog 86 on the slide 82 throws over the bell crank. However, the vibrator 54 is not yet in contact with the first distributing roller 51. This contact is efiectei only. after the slide has completed its ascending motion, the dog 86 engaging the bellcrank 88 and throwing it over to place the vibrator 54 against the first distributing roller 51.

The moment at which the sector 90 separates the vibrator 54 from the ductor roller 50 is varied by adjusting the cam sector 90 with respect to the arm 83 through the toothed sector 92 and the spring catch 9|. By these means, the width of the strip of ink taken from the ductor cylinder 50 in the direction of its perimeter is varied as desired.

When it is desired to arrest the carriage I, the coupling C between the pulley I and the main driving shaft 3 is thrown out in the usual manner. When the handle 20 is now turned in the direction of the arrow 23 in Figl- 2, and into the position illustrated in Fig. 3, and the clearance between the parts 2| and 22 has become exhausted, the arm I6 moves the clutch plate II into engagement with the clutch member I0 on the pulley I and so the pinion I3 on the sleeve I2 is rotated, notwithstanding the main driving shaft being arrested. The pinion operates the inking apparatus A through the means described notwithstanding the stopping of the carriage I, and this is useful for applying ink of a different color, or for regulating the supply of the ink while the rotary elements of the inking apparatus r0- tate at uniform velocity. When the handle 20 is moved into the position illustrated in Fig. 3 from that in Fig. 2, its dog 25, through the pin or roller 26 on the bracket 21, shifts the rod 28 in the direction of the arrow. I04, Fig. 1, and into the position illustrated in Fig. 4, independently of the cam plate 15 which may assume any position at this moment, and by these means, as described, the inkers 58 are elevated by the turning of the handle 20 so that they will not ink the form if the carriage stops below the inkers.

Upon the continued operation of the inking apparatus A the ductor cylinder 50 is rotated from spur gear 48 through pawl 52, so that the vibrator 54 can take any quantity of ink from the ductor cylinder 50 and transfer it to the first distributing roller 51, by moving the vibrator 54 away form the ductor roller 50, and against the distributing roller 51, by the handle I05 of the bellcrank 88.

Since the ductor cylinder 50 continues its rotation after the carriage I has been arrested, the

'doctor blade I08 can also be adjusted as desired.

If it is desired to arrest the ductor cylinder 50 without interfering with the operation of the other elements in the inking apparatus A, the hand wheel 84 is pushed in the direction of the arrow 86, Fig. 5, whereby the ductor cylinder is disconnected from the spur gear 48, as described, and can now be turned as desired by the hand wheel 84.

cluding the regulating means I3 etc., by which the inking apparatus A is driven in conformity with the movement of the carriage I, as described. As the regulating means upon the stopping of the carriage remains standingexactly in that position which corresponds to the position of the carriage I, the drive of the inking apparatus A is operated exactly in conformity with the motion of the carriage I when the carriage is restarted.

' If the invention is adapted not to a stop cyl inder machine, as illustrated but to a single or double-revolution cylinder machine, byway of example, whose velocity curve is illustrated at I06 in Fig. S3, in dotted lines, the regulating means I3 etc. is preferably so constructed that the fulllines curve Hill is produced, allowing the carriage I, with the form, to be reversed at the front end at a short distance from the last inker 58.

It will appear from the foregoing description that the drive for the inking apparatus according to the invention has the advantage that the carriage is not required to drive the inking apparatus, i. e., the rotation of the inking elements is not decelerated until the elements stop, and then the elements are accelerated again. The consequence is that a printing machine according to the invention has a much lower power demand than one equipped with the known inking apparatus and can be operated at a much faster rate, the more so as the carriage does not drive the inking apparatus' The rotation of the elements in the inking apparatus in the same direction is favorable with respect to the distributing rollers 51 since they are not subjected to alternating but to unidirectional stress.
